If i’m not mistaken—using MIT’s OWC as an example—these courses are basically carbon copies of lectures they give their students. The instructors are still teaching on the campus to IRL students. The only difference is that these are then put online for easy access a la open source projects. So, to answer your question, the money spent to produce online (o) lectures is equal to campus (c) lectures—without taking into labor hours to upload and edit. Therefore, O + C = $T.
